Data from The g Factor: The Science of Mental Ability (1998), by Arthur Jensen:

> Identical twins reared in the same family are much more similar in IQ (corr .86) than fraternal twins reared in the same family (corr .60).

> Identical twins reared in separate families are substantially more similar in IQ (corr .75) even than fraternal twins reared in the same family (corr .60).

> Biological siblings reared in separate families have a .24 IQ correlation in childhood, which increases to .47 by the time they reach adulthood, very near the .49 IQ correlation of siblings reared together.

> Unrelated children adopted into the same family have a .25 IQ corellation in childhood, WHICH DIMINISHES TO .01 BY THE TIME THEY REACH ADULTHOOD.

> By adulthood, Blacks adopted into middle-class White families had IQs averaging 89.4, just slightly above the average of 88 for Blacks of the North Central U.S. region from which they originated. This was 9 IQ points below the average of the adopted Black/White hybrids (98.5) in the same families, 16 points below the adopted Whites (105.6), and 20 points below the White biological offspring (109.4).

These results from many large and carefuly scrutinized studies demonstrate with certainty that intelligence and academic attainment, particularly the racial differences thereof, depend much more strongly on genetic inheritance than on family/environmental influences.

Biological correlates:

> IQ correlates about .7 to .8 with the rate which the brain metabolizes glucose, ascertained by studies employing positron emission tomography to record brain processes. More intelligent people's brain's utilize glucose more efficiently and therefore slower. At the extreme, people who are mentally retarded or have Down's Syndrome consume glucose 30% faster than normal.

> IQ correlates .6 to .7 with a person's speed at various types of reaction-time tests.

> IQ correlates .5 to .54 with object recognition tests, in which an object is flashed very briefly on a screen and must be recognized.

> The IQ subtests which depend the least upon culture (i.e. on experience and knowledge) are the ones which evince the highest degree of heritability and the ones for which the racial differences are greatest; e.g. raven's progressive matrices (g-corr .8) and backwards recitation of numbers (g-corr .6).

> The robust hereditarian principle of regression to the mean in the offspring of anomalous parents is plainly evident in the offspring of Whites and Blacks: The offspring of IQ-120 Whites regress to an average of 110, midway toward their racial average of 100; while the offspring of IQ-120 Blacks regress to an average of 100, midway toward their racial average (in the U.S.) of 85. The offspring of IQ-70 Whites "regress" to an average of 85; while the offspring of IQ-70 Blacks "regress" to an average of 78.

> Children of high income Blacks have lower IQs than children of low income Whites. The SAT scores of Black children who come from households with incomes of $70,000 or more are lower than that of White children from households with incomes of $20,000 or less, in spite of all the racial preferences enjoyed by the Blacks.

I find it interesting we cannot discuss this sort of topic, because it's probably the only way to resolve our problems along these lines.

The reason is that one side, having imported a ton of people to ensure there's no dominant culture to insist they stop being self-focused, now cannot bear the thought that any research shows that diversity is anything but 100% good and we as people are not anything but 100% equal (except for "chance" of nature) among classes, races, ethnicities, genders, and probably some other stuff I've forgotten.

Reminds me of my Slashdot post this morning:

Advocates call the law a necessary control on hate speech in an age where the Internet makes the spread of messages easier and faster. Opponents say it's censorship and has no place in a free society.

Not only are we divided on whether it should be legal, we are divided on what it should be.

If you have any knowledge of survival of the fittest, you would understand the top survive. You seem like a typical scared idiot who is more concerned with destroying than collaborating. I think sterilizing you would be a better idea, but your ideals does a better job of that.

Brain size is meaningless; the cro-magnon had a larger frontal lobes than the modern man. The Neanderthal had a larger brain (period!). The IQ tests were intended to test for stupidity, not intelligence, however even the score of 89 does not place them in the original 'moron' or 'Borderline deficiency' rankings. In fact, most European immigrants who sat this test when it was released were deported because they fell into the 'moron' category (50-69) and below. We can conclude from that that Europeans are morons. Hey, why not. We're drawing bullshit conclusions from black people so why not apply the same logic for Europeans?

The truth is that 'black' people are not a single race of people, and members of two Bantu tribes-- 500km apart-- have more genetic difference than a European and an East Asian.

All this aside, your idea of 'white' includes Middle-Eastern people alongside Europeans. Why don't we see the split test scores? Don't say it's because they're both Caucasian, because then there is no reason to exclude Indians who are also classified as Caucasian, but fall under the 'Asian' grouping. The truth is that if this was the case, we'd see that the Europeans are extremely inferior to their Middle-Eastern counterparts. You know, the ones who developed civilization while the Europeans were still hiding in their caves. To this day, you still worship their gods and prophets.

Fuck this post, because it's all garbage. Assess people on who they are as a person rather than their ability on an exam.

Instead of wondering which race to get rid of, why not use this data for the advancement of the planet as a whole, why do we HAVE to have a superior race, why not use the advantages of every race to benefit us all as a whole?

Even if it holds that one race has a slightly lower IQ on average, you still can't discriminate, simply because there are frequent outliers, and with IQ the sigma is not so small. Therefore, such data gives no reason to judge a single person based on their race.One thing I do agree with is that races exist, and are statistically different. Denying that is kind of stupid.

Being a black male born in Africa It’s my personal opinion that there are many social issues that contribute to low black IQ scores. I believe many African Americans are stuck in a slave mentality. That is they subconsciously think they are inferior. Being that my family thru generations has never experienced I think makes a difference in how we view ourselves. For instance in my family my dad and two brothers have PhDs. My mom and one of my sisters are nurses; my other sister is an accountant. My wife is Jamaican and was on the dean’s list last year she is studying for her BSN in nursing. Both of my sons do well in school (10yrs & 5yrs) my oldest gets mostly A's and tutors other kids in his grade. In fact there is no one I know in the African community that I’m in that has anything less than a 4yr College degree if they don’t have one there working on it.

Race is real and so is the ongoing genocide of the white race is every white nation on earth:

ASIA FOR THE ASIANS, AFRICA FOR THE AFRICANS, WHITE COUNTRIES FOR EVERYBODY!

Everybody says there is this RACE problem. Everybody says this RACE problem will be solved when the third world pours into EVERY white country and ONLY into white countries.

The Netherlands and Belgium are just as crowded as Japan or Taiwan, but nobody says Japan or Taiwan will solve this RACE problem by bringing in millions of third worlders and quote assimilating unquote with them.

Everybody says the final solution to this RACE problem is for EVERY white country and ONLY white countries to “assimilate,” i.e., intermarry, with all those non-whites.

What if I said there was this RACE problem and this RACE problem would be solved only if hundreds of millions of non-blacks were brought into EVERY black country and ONLY into black countries?

How long would it take anyone to realize I’m not talking about a RACE problem. I am talking about the final solution to the BLACK problem?

And how long would it take any sane black man to notice this and what kind of psycho black man wouldn’t object to this?

But if I tell that obvious truth about the ongoing program of genocide against my race, the white race, Liberals and respectable conservatives agree that I am a naziwhowantstokillsixmillionjews.

Think about this, those who use the argument that there are no racial differences genetically, how are they coming up with the arbitrary conditions to make such an argument. Are they using the WHOLE genome, or just certain genes, such as those that give rise to physical appearance.

ok, perfect. But if we viewed blacks based on the content of their character instead of the color of their skin, they would be screwed. Blacks overperform in every negative aspect of society and underperform in all areas positive to humanity.

you could not be more wrong. Only 1 in 10 blacks score above average for whites. Would you want someone with an 80 IQ performing your life and death surgery because some idiot said intelligence is not that big a deal? Check out the bell curve of IQs for blacks and white superimposed upon one another. If that does not prove they are a different species, then you are simply a denier of reality.

The fellow is entitled to an opinion and furthermore also entitled to his own interpretation of what is said. It is rather uncouth to get aggressively abusive because you do not share the same opinion. You need to keep your comment civil even though you rage hormones seem to get the better of you. Unlike you? I'm not hiding my identity.

Here is a very basic lay down of evolutionary genetics. All hominids originated in Africa this is a fact. Because of advances in DNA theories are always changing. The first hominids advanced out of Africa over 1 million years ago. They gave rise to Neanderthals and other subspecies of humanoids. Most of all modern non African peoples DNA comes from two migrations out of AFRICA by homosapiens between 80 and 40 thousand years ago by groups that maybe numbered fewer then 100 people. These people did intermixed somewhat with hominids that had earlier migrated into Eurasia like Neanderthals contributing up to 10 percent of their DNA in some populations.

So at least two migrations of homo sapiens occurred into Eurasia between 80 to 40 thousand years ago from Africa. There was some hybridization with Neanderthals and at least one or two hominid species that had lived in Eurasia for up to one million years previously but it seems from current data minimal. Now comes the Ice Age between 30 to 10 thousand years ago. This is where we see a major cognitive leap forward in cognitive performance. The ancestors of asians (north asian) and Europeans where isolated in the most extreme glacial tundra environment the world has maybe yet seen. Basically you couldn't be a dummy and survive you had to be innovative and intelligent. Now 10000 years ago we get the agricultural revolution. In the area thats ironically Iraq you get settled communities government social classes and RELIGION. Now here's what I believe. RELIGION is someone's take on REALITY. Religion says the world is 6000 years old and denies evidence like evolution archeology and molecular biology. Well isn't Fabian socialism utopian socialism communism all a type of religion? And when its a religion if you say anything that contradicts their reality you get"burned at the stake." I find this with nearly all white people after 50 years of TV brainwashing "Kim Kardashian anyone?" So you have Israel with many people with immesurable iqs and lets say the Central African Republic where its likely a lot less right where people are being slaughtered for RELIGION while in the West we have a class structure and an upper class that can live in denial of reality. Obama anyone about to let Iran have"nuclear energy item nuclear bomb!" I hope there is a God because God help us all! Reality people. I know its hard trust me. But here's an analogy. In nature stupidity leads to being eaten. PERIOD.

The idea that black males predominately are of higher testosterone levels is totally contradicted by the behaviors associated therewith, which are reflective of feminine, emotional rather than logical functioning. The alpha male among primates, possessing a high level of testosterone, does not lash out without reason on the basis of emotional stimuli, but acts to correct and discourage repetition of such behavior from those who do act impulsively and create disorder within the community.

"We observed higher serum estradiol concentrations and higher estradiol/SHBG ratios in non-Hispanic black than in non-Hispanic white or Mexican-American men, a difference that was pronounced in young and mid-adulthood."
